What a delight, having That Mitchell and Webb Sound (Radio 4) back on the radio. Yesterday's show was consistently very funny indeed; quite an achievement given that 14 – yes, 14 – writers worked on it. The best sketches looked askance at current trends. Julius Caesar was advised to give himself more gravitas by referring to himself in the third person, in Facebook mode, and the results were a hilarious tangle.

But I particularly liked hearing about the iReckon, a brain implant that means you don't have to think."Making thoughts used to be boring," said Mitchell, "I had to look at stuff and talk to people." Webb sounded just as enthusiastic: "I can download all my thoughts from the internet, just like racists and David Icke." There are thousands of applications, we heard ("sad, happy, paranoid, 80s"), and you can play them on shuffle.

There was fun, too, in an ideas meeting to come up with the next Strictly Come Dancing. "Let's mind-smash this thing," cried Mitchell, prefacing a list that included Indiana Jones and the Temple of Bergerac, One Flew Over the Cuckoo's Bagpuss, and All You Ever Wanted to Know About Sex But Were Afraid to Pebble Mill At One.
